Bedfordshire and its Dragonflies
The county of Bedfordshire
Bedfordshire and its dragonflies and damselflies are intricately connected through the county’s many rivers and lakes. It is one of UK’s smaller counties, situated in the south-east of England, but with a range of habitats that are well suited to dragonflies and damselflies it supports a variety of species including several rarities.
Odonata are creatures whose existence is centred on producing their offspring. Their life cycle is inextricably linked with water, and they are wholly dependent on it. Dragonflies lay their eggs in water, and the resulting larvae spend the majority of their lives as aquatic insects, before they eventually emerge to briefly take to the air and breed to begin the next generation.
Bedfordshire’s waters
The most significant watercourse in Bedfordshire is the River Great Ouse, traversing the north of the county, entering at Turvey at the west and leaving near Wyboston at the east. The River Ivel and River Flit flow through the south-east before joining the River Great Ouse north of Sandy. The River Lea begins in Bedfordshire, winding in a south-easterly direction before leaving the county to become a tributary to the River Thames.
There are a many lakes in the county, but these are man-made. Bedfordshire has a long history as the centre of brick making in the UK, and many lakes are former clay pits that have flooded. These are mainly in the Marson Vale area, between Kempston Hardwick and Brogborough. Further to the north of the county, lakes are often former gravel pits, some dating from the Second World War where they were used to provide construction materials for air strips.
Often these lakes are used for leisure facilities, but some are set aside as nature reserves. They make excellent habitats for Odonata provided the water has plenty of emergent vegetation for larvae to leave the water, and the surrounding area supports other insect life for adult dragonflies to feed upon.
Bedfordshire’s waters are in the main of good quality, supporting 24 breeding species of dragonflies and damselflies.

Bedfordshire’s dragonflies
There are many important sites for Odonata in Bedfordshire:
Bedfordshire and its dragonflies changes over time, and as conservation interest grows more sites are being developed, such as the Forest of Marston Vale, this is good news for any nature lover. Many other sites exist, please let me know of your favourites.
In these pages you can find links to the dragonflies and damselflies that may be seen within Bedfordshire’s borders. I have included links to proven breeding species, but migrants do occasionally venture into darkest Bedfordshire, and I will put pages up for those species as they turn up.
The checklist
Travelling around Bedfordshire and photographing its dragonflies is an interesting challenge, with some species found only in very localised areas. So far, I’ve photographed 21 of the 24 species occurring in Bedfordshire, leaving a few more to find.
Checklists are useful indicators of species that are known to breed or that may be seen in an area, they can be quite fluid however and may change over time. Some species populations are small and very fragile, and individuals may not be recorded for several years.
It is probable that the Scarce Blue-tailed Damselfly – Ischnura pumilio is now extinct in Bedfordshire following the demise of its only habitat at Sundon Chalk Quarry. It has not been seen since 2003 and is no longer included in the county list.
But as if to make up for it, new species like the Downy Emerald dragonfly – Cordulia aenea and Willow Emerald Damselfly – Chalcolestes viridis are now establishing themselves in Bedfordshire.
